AUTUMEATIC LUBRICATOR.

To all whom; it may concern Be it known-that I MAXIMILIA-N- Dam sense, a citizeno f the German Empire, residing at Herdelberg 1n the Grand Duchy of Baden, Germany, have invented certain new and useful Improvementsuin Automatic Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which itappertainsto make and use the same.

This invention relates to automatic lubricators for the wearing. surfaces of machine of elevatorsi conveyers and the like may be autoniatical y operated bymeans of pro-- jections provided alongsideof,- or in the track of'the vehicle: with-the aidvof theme-- tion: of the elevator itsel f.

Among other advantages intended'to-be attained by the'use'of sueh arppairatus isthe delivery 'of the lirbricant only at considerable intervals of time. The intermittent operation heretofore effected: by the: pro-- jeetions referrexlv :to.- is' effected in the present invention by actuating. the thezluibricastor by means of. apparatus: which frictionelly engages the guide rail of t-hefelevaton, and has a limited oscillating motion due-to up and down movement of the: elevator; the friction i device running with it upon the guide rail. Each of *the -oscillationswor"two mmore-consecutive oscillations may be utilized for the production of: a single workings stroke of 'an oil pump, a resser other-delivery mechanlsnio The'motion of the. elevatoris-xthusutilized for imparting" an intermittent action to the hibricator" without requiring an excessive number of parts-or= anycomplicated apparatus:-

- An important advantage-of the present invention is that it dispenses with the necessity of attachingprqections to the guide rail which in consequence ofth'e variation of the rofile of the rail used, according to the ma er and the kind and shape of the lift space, often caused very considerable difficulties.

In the accompanying drawing which illustrates one form of the invention, Figure l is a side elevation of the lubricator and a S'pecification'of Hatters-Patent. Application fi1edJu1y-29, 1912; Serial No 711,988.

section of the guide rail. Fig; 2is a sectional View of the device shown in Fig. 1. Referring to the drawing by letters of reference, a represents the distributing block for spreading, the lubricant from the container 6 which is fastened to said block. 0 indicates a small plunger pump, the piston O'f'W'h'lGh' moves in and out under the influence of the oscillating lever f which is fast on the shaft 6. Upon this shaft 6 are screwed fast two. lever arms 9 and h constituting the frictional actuating device. These levers gand h are resilient inorder to press the friction blocks 71 and on their ends againstthe guide will of the lift.

The: operation of the device is as follows: As soon as the lubricating apparatus connected with. the-liftmoves. for instance in the direction-of the arrow on on Fig. 1, the levers g and h revolve aboutv the shaft e throwing the free ends of the levers upward. until the piston offithe plunger pump c is-moved. to the end ofits inward stroke.

The parts of the lubricating apparatus remain in-this positionasrl .as the-motion con-tinuesin the direction 0 -the arrow m. As soon as the elevator commences its jourmy. in the opposite direction, the free ends of the levers g and h, in-consequence of the frictional engagement of the blocks 2' and k with the guide rail, are moved down, so that 'the pistonof t-hepqump o is moved outward. Twoturnings in the direction of=the travel ,will, .therefore, cause one. stroke of the oil pemp'- lubricating mechanism may obviously be so arranggd-thatlat eachmotion,

a acomplete stroke of the piston shall be effected.-. The :use ofafrict'ioii piece or friction pieces on' .the side surfaces. of the guide rail orof two pieces travelin upon the side surfaces of. the guide. rail has -the advantageth'at the necessary play requisite for the guidance of thelift in thegmdingdever f is connected to the piston, so that when the piston has reached the end-of its inward stroke the arms 9 and h of the oscillatory device will be prevented from further upward movement, and when the piston reaches the end. of its outward stroke,'said ar1ns will be prevented from further downward movement.

It will be understood of course that various changes may be made in the details and HPZlngBIiiQnt of parts without departing from the spirit and scope of my invention, and that the invention is not limited in its application to the guide rails. of elevators, though the illustrated embodiment is especially designed and adapted for such use; but obviously the invention is applicable to various other uses, and the term guide rail as used in the specification and claims may refer to any similar or equivalent structure to which the invention may be applied; ience I do not desire to be limited to the specific form of device shown and described, nor restricted in the application of the invention to the specific use stated.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. The combination with a guide rail for an elevator, of a lubricant container adapted to be reciprocated along said guide rail, means for discharging the lubricant'from the container upon the guide rail, and an 05-- cillatory device frictionally engaging said guide rail for actuating said discharging means.

2. The combination with a guide rail for an elevator, of a lubricant container-adapted to be reciprocated along said guide rail, means for discharging the lubricant from the container upon the guide rail, an oscillatory device frictionally engaging said guide rail for actuating said discharging means, and means whereby the movement of sa id oscillatory device is limited in both directions to prevent the portion thereof which frictionally engages the guide rail from leaving the latter. I

3. The combination with a guide rail for an elevator, of a lubricant container adapted to be reciprocated along said guide rail pump for discharging the lubricant from container upon the guide rail, an oscillatory device frictionally engaging said guide rail for actuating said pump, and means whereby the stroke of the latter is limited to prevent the portion of said oscillatory device which frictionally engages the guide rail from leaving the latter.

4. The combination with a guide rail for an elevator, of a lubricantcontainer adapted to be reciprocated along said guide rail, means for discharging the lubricant from the container upon the guide rail, and an oscilla-tory device having a resilient portion frictio-nally engaging the guide rail for actuating said discharging means.

5. The combination with a guide rail for an elevator, of a lubricant container adapted to be reciprocated along said guide rail, means for discharging the lubricant from the container upon the guide rail, and an oscillatory device having a pair of resilientarms frictionally engaging the opposite sides of the guide rail for actuating said discharging means.

. 6. An automatic guide-rail lubricating device comprising a lubricant container movable along the uide-rail, means carried by said container r discharging the lubricanttherefrom, and a rocking lever having one arm arranged to contactwith said guide rail and another arm connected with said discharging means, whereby the lubricant is distributed by frictional engagement of the rocking lever with the guide-rail as the container travels back and forth.

'7. An automatic guide rail lubricating de vice comprising a lubricant container movable along the guide-ra-il, a pump carried by said container for discharging the lubricant therefrom, and a rocking lever having one arm arranged to contact with said guide-rail and another arm connected to said pump.

8. An automatic guide-rail lubricating device comprising a lubricant container movable along the guide-rail, a pump carried by said container for discharging the lubricant therefrom and a rocking lover having one arm arranged to contact with opposite sides of said uide rail and another arm connected to said pump, whereby the lubricant is distributed by frictional engagement of the rocking lever with t", guide rail as the container travels back and forth.

In testimony whereof I affix my signature in the presence of two witnesses.
